no fish are smart - not compared to mammals anyhow. However - any "wild trout" is heads & shoulders above a stocked fish in the wary dept.

You just cannot stomp up to a stream & regularly catch a"wild fish" like so many opening day guys think. Not even most stocked fish will handle this kind of pressure

By day three - these fish were hungry - especially stocked fish (which you likely caught - if the lower fins are worn - its a stock fish) and the slack in pressure made the difference.

The best thing that ever happend in my section of NY was the Year Round opening of my favorite stream. Opening day crowds went away - and most outsiders think that the stream "must get fished alot" because its open year round - WRONG.
